BINDER.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed April 17,1906- s 312,115.

To all whom it may concern:

Be it known that I, WILLIAM HARRISON BAYLES, a citizen of the UnitedStates of America, residing at Manhattan, in the city, county, and Stateof New York, have invented a new and useful Improvement in Binders, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming part of the same.

Figure 1 is a plan view'of a binder embodying my invention, the coversbeing broken to condense the figure. Fig. 2 is a section through such acover holding a series of magazines on line 2-2 of Fig. 1. Fig. 3 is adetached view in perspective of apart of one member of the clamp Iordinarily employ. Fig. 4 is a similar view of the thumbscrew, thesleeve and the opposite member of the clamp. Fig. 5 is a front elevationof a modified form of clamp member I may employ. Fig. 6 is a view inperspective of a dividing holding strip I may employ with the clamp ofFig. 5, v

to accommodate a single pamphlet. Fig. 7 is a view in perspective ofbroken portions of the devices of Figs. 5 and 6, showing the manner oftheir combination to form a stop. Fig. 8 is a view in perspective, ofanother form of stop. Fig. 9 is a vertical, sectional view of a clamp,showing the stop of Fig. 8, as it is arranged in use.

My invention relates to binders, especially adapted to hold one or aseries of pamphlets (particularly a series) in convenient covers forready reference, but at the same time protected from unnecessary wearand, as to the series, so bound together that they will be kept togetherand may be handled all at once and easily examined without the necessityof separate handling for each individual pamphlet. Such a device to beacceptable must be adjustable to hold pamphlets of varying thickness, itmust hold them firmly, it must be so simple that it will not get out oforder and will not need a skilled bookbinder to operate, and it mustalso be so inexpensive as to Warrant its use as a temporary expedient.

The device of my invention consists primarily in a clamp having rigidextreme members and intermediate pieces adapted to be moved on asuitable bar and to be placed between each two members of the series ofpamphlets to be bound in it. In the one shown I have used an ordinarypasteboard cover having two sides, 0 G, and a back, B. The cover is notabsolutely esssential, but its use is preferred to protect the matter tobe bound. To this cover I secure two clamps, or binders. I find itconvenient and preferable to secure them to a flat metal plate.

The-clamp consists of a rigid base. plate, I, two rigid clamp members,0, c, which slide in and out in recesses, 7*, formed in the base plate,a cross bar, b, formed of a hollow tube, one end secured to one clamp Imember, 0, a sleeve, 8, secured to the other clamp member, 0, and athumb screw, S, which projects into the sleeve, 3, and takes in a threadcut on the interior of the tube or bar, 12. For firm holding I employtwo of such clamps, one at or near each extremity of the binder.

On the bar, I), I arrange a series of intermediate strips, 01, aperturedto slide easily on the bars and, preferably provided with holding-teeth,t, projecting at each side, to engage the pamphlets to be bound.

In some styles, I form the clamp member, c of a projecting part of thebase plate, P, cut to suitable shape, and turned up to about a rightangle with the remainder of the base as shown in Fig. 9. Then of coursethe other, a, is the only adjustable outer clamp member.

To use the binder, I slacken the thumb screws, place a pamphlet againstone clamp membersay 0, push one strip, d, closely against the other sideof the pamphlet, place a second pamphlet against said strip, d, push upanother strip, 01, against the other side of the second pamphlet andcontinue till I have placed as many pamphlets as I wish and then turndown the thumb screw till the teeth of the second clamp member, 0, arebrought tightly against the other side of the last pamphlet placed, whenthey will all be held tightly bound together and ready for reference orconvenient storing, if not to be used for the moment.

A simple clamp bearing against the outer side of each of the outerpamphlets would nothold the intermediate ones firmly. They would slipout and release the whole bundle. But in this device, each bundle isheld on each side and the holding means are each firmly secured to theclamp, by being pierced by and held on the cross bar, b, the resultbeing that the whole number are held firmly in position.

I do not limit myself to the exact form of clamp shown, nor do I limitmyself to strips reaching from one clamp to the other. They might beshort pieces,

but they are more convenient to adjust when they are long enough to besupported at each end by the proximate bar.

The adjustability of the clamp members could be such as to permit themto be adjusted close enough one to the other to hold a single pamphlet,but in practice this is not convenient. If only one or two pamphlets areto be bound, blocks of wood or pasteboard may be inserted between theouter strip, d, and one of the clamp members, 0, or c, or I may use theform of device shown in Figs. 8 and 9.

I may cut notches, n, in the bar, I), as shown in Fig. 5, and slot astrip, (1 (preferably made heavier and more rigid than the others,) asshown in Fig. 6. Then having placed the single pamphlet or the number IWish to bind, insufficient to fill the binder, I push the strip, d, andany others that may be between it and the pamphlets, as close to theadjustable clamp member as ordinary pressure will permit and force thestrip d, up or down till the edges, e, of the slots enter the notches,n, when strip d will be held from lateral movement and will-in turn actas an outer clamp member against which the stress of the adjustableclamp member may be brought to bear by turning down the thumb screw asbefore, thus locking in place the single pamphlet or the small number ofpamphlets then to be bound.

In place of a stop of the character described, I may use that shown inFigs. 8 and 9. In that arrangement, the base plate, P, is provided witha series of recesses or stop holes, h, and a stop, S, is used. It has anupright plate, d apertured as shown to permit its being slipped upon thebar, b, a base plate, (1 at about a right angle to plate, d and feet orpins, p, spaced and shaped to register with and enter the stop holes, h.I prefer to arrange it on the bar, b, with some strips, d, on each sideof it, but with its horizontal plate, d, extending in a directionreverse to that in which I place 11", when I use the stop of Fig. 10.Then, having placed one or a small number of pamphlets as before, Ipress the stop, d up close to it or them, as I did with d, fitting thepins, p, into the holes, h, whereupon I may bind what I have by turningdown the thumb screw, S, as described. By using two stops as outerclamping members, and one or more clamping strips between, I mightdispense with clamp members, 0, 0, but it would not be so convenient. v

For completeness, some form of stop is desirable, but I do not limitmyself to the employment of either form shown, nor do I limit myself toa construction in which the clamping strips, d, are mounted on the crossbar in which the binding screw works.

What I claim and desire to secure by Letters Patent is:

1-. In a binder, the combination of a rigid base plate, two

outer clamp members, one of which is movable to or from forth.

outer clamp members, one of which is movable to or from the other, across bar extending from one clamp member, a sleeve extending from theother clamp member, a thumb screw extending into the sleeve and engaginga thread cut in the cross bar and an intermediate adjustable clampingstrip mounted upon the cross bar, all substantially as set forth. I

3. In a hinder, the combination of a rigid base plate, two outer clampmembers, one of which is movable to or from the other, means for forcingone toward the other, an adjustable intermediate clamping strip, adaptedto be inserted between two pamphlets, means for holding said 2. In abinder, the combination of a rigid base plate, two

clamping strip to the base plate, and an intermediate stop adapted tolimit the lateral movement of the said intermediate strip, allsubstantially as set forth.

4. In a hinder, the combination of a rigid base plate, two outer clampmembers, one of which is movable to or from the other, means for forcingone toward the other, a series of adjustable, intermediate clampingstrips each adapted to be inserted between two pamphlets, and means forhol l ing said clamping strips to the base plate, all substantially asset forth.
